Mechanism of action

Nitric oxide is a potent selective pulmonary vasodilator that reduces pulmonary vascular resistance and improves ventilation-perfusion matching in the lungs. By preferentially dilating vessels in well-ventilated lung regions, iNO enhances oxygen uptake and reduces intrapulmonary shunting, thereby improving arterial oxygenation in critically ill patients.
